Fanstar is a pretty good site (I have played in all the others, Yahoo, CBS, ESPN, Sandbox). So far, I have not found one better that suits all our needs. I do have to manually handle trades, however, they may be upgrading this. I'm commish of our league, Fanstar has been mostly a football site until last year. They started off a bit rough, however, very quickly they were pretty good. They plan to do some additional upgrades end of this month. The only major issue I have is, their drafting tool is not good for auction drafting. I'm switching our league this year to auction drafting and I'm trying to find a free site to hold our draft, but will go back and use Fanstar for the season. Anyone know of a good free site, with a good auction drafting tool? I have checked out Fantasy Auctioneer, which is fantastic, however, it does not allow slow draft auction and they charge a small fee.
By the way, you can go set up a league for free to test the site, even run a mock draft.
